THIS HAZARDOUS WEATHER OUTLOOK IS FOR WEST CENTRAL AND SOUTHWEST
FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

...THUNDERSTORM IMPACT...
COPIOUS AMOUNTS OF TROPICAL MOISTURE STREAMING INTO THE REGION
WILL SUPPORT WIDESPREAD SHOWERS AND ISOLATED THUNDERSTORMS OVER
THE REGION TODAY AND TONIGHT. THUNDERSTORMS WILL BE CAPABLE OF
PRODUCING VERY HEAVY DOWNPOURS...DEADLY LIGHTNING STRIKES AND
STRONG GUSTY WINDS AS THE STORMS MOVE TO THE NORTH AND NORTHEAST
AROUND 20 MPH. REMEMBER IF LIGHTNING IS OBSERVED OR THUNDER IS
HEARD MOVE INDOORS IMMEDIATELY.

...FLOOD IMPACT...
LOCALLY HEAVY RAINFALL WILL BE POSSIBLE TODAY AND TONIGHT
ESPECIALLY WHERE THE TRAINING OF STORMS OCCUR OVER THE
SAME AREA. RAINFALL AMOUNTS OF 2 TO 3 INCHES OVER A SHORT
PERIOD OF TIME WILL BE POSSIBLE WHICH WILL PRODUCE FLOODING
OF LOW LYING AND POOR DRAINAGE AREAS AS WELL AS THE PONDING
OF WATER ON ROADWAYS. MOTORISTS SHOULD SLOW DOWN AND EXERCISE
EXTREME CAUTION IF ENCOUNTERING HEAVY RAIN TODAY AND TONIGHT.

...RIP CURRENT IMPACT...
AN INCREASING SOUTH TO SOUTHWEST WIND FLOW ALONG WITH
BUILDING SEAS AND INCREASING SURF WILL CREATE A HIGH RISK
OF RIP CURRENTS ALONG AREA BEACHES THROUGH TONIGHT.

TO AVOID GETTING CAUGHT IN A RIP CURRENT...SWIM AT GUARDED BEACHES
AND HEED THE ADVICE OF THE BEACH PATROL.  AT UNGUARDED BEACHES AND
NEAR PIERS...JETTIES...AND INLETS...DO NOT GO INTO THE SURF MUCH
ABOVE YOUR KNEES.

...MARINE IMPACTS...
SOUTH TO SOUTHWEST WINDS INCREASING TO AROUND 20 KNOTS WITH
HIGHER GUSTS IN THE VICINITY OF THUNDERSTORMS COMBINED WITH
BUILDING SEAS WILL CREATE HAZARDOUS BOATING CONDITIONS FOR SMALL
CRAFT OPERATORS AND SMALL CRAFT ADVISORY HEADLINES HAVE BEEN
POSTED FOR THE NEAR AND OFFSHORE WATERS FROM TARPON SPRINGS SOUTH
TO BONITA BEACH OUT 60 NM WHICH INCLUDES THE TAMPA BAY AND
CHARLOTTE HARBOR WATERS THROUGH TONIGHT. FISHERMEN AND OTHER
SMALL CRAFT OPERATORS MAY WANT TO POSTPONE TRIPS INTO THE GULF
UNTIL CONDITIONS IMPROVE.

...WATERSPOUT IMPACT...
INCREASING WIND SHEAR WITHIN THE ATMOSPHERE WILL BRING AN
INCREASED RISK FOR WATERSPOUTS OVER THE ADJACENT GULF WATERS
LATE TONIGHT THROUGH THURSDAY.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.

TROPICAL DEPRESSION NINE LOCATED OVER THE SOUTHEASTERN GULF
OF MEXICO EARLY THIS MORNING IS FORECAST TO MOVE NORTH AND
INTENSIFY INTO A TROPICAL STORM LATER TODAY. THIS SYSTEM IS THEN
FORECAST TO MOVE TO NORTHEASTWARD OVER THE EASTERN GULF OF MEXICO
TONIGHT AND THURSDAY BEFORE MOVING ONSHORE AND ACROSS THE
NORTHERN FLORIDA PENINSULA THURSDAY NIGHT. COPIOUS AMOUNTS
OF TROPICAL MOISTURE ASSOCIATED WITH THIS SYSTEM WILL SUPPORT
WIDESPREAD HEAVY RAINS AND SQUALLS OVER THE REGION ON THURSDAY
ESPECIALLY ALONG COASTAL LOCATIONS FROM TAMPA NORTH INTO THE
NATURE COAST WHERE AN INCREASED THREAT OF FLOODING WILL EXIST AS
BANDS OF HEAVY RAIN AND STORMS MOVE OVER THE REGION. AT THE
PRESENT TIME WIDESPREAD RAINFALL AMOUNTS OF 4 TO 6 INCHES WILL
BE POSSIBLE OVER INTERIOR SECTIONS OF WEST CENTRAL FLORIDA TODAY
THROUGH SATURDAY...WITH 6 TO 10 INCH AMOUNTS POSSIBLE ALONG
COASTAL LOCATIONS FROM SAINT PETERSBURG NORTH TO CEDAR KEY.

IN ADDITION TO THE HEAVY RAIN AND FLOODING THREAT INCREASING WIND
SHEAR WITHIN THE ATMOSPHERE WILL BRING AN INCREASED RISK OF
TORNADOES LATER TONIGHT THROUGH THURSDAY AS THE TROPICAL STORM
APPROACHES FLORIDA. THE INCREASING SOUTH TO SOUTHWEST WIND FLOW
WILL ALSO SUPPORT AN INCREASING STORM SURGE THREAT ALONG THE
COAST...WITH THE HIGHEST STORM SURGE LIKELY TO FOCUS ALONG THE
NATURE COAST FROM HOMOSASSA NORTH TO CEDAR KEY CLOSEST TO THE
TRACK OF THE STORM DURING LATER TONIGHT THROUGH THURSDAY.

INCREASING SOUTH TO SOUTHWEST WINDS WILL ALSO HELP TO BUILD SEAS
SIGNIFICANTLY OVER THE GULF WATERS...WHICH IN TURN WILL LEAD TO
VERY HAZARDOUS BOATING CONDITIONS FOR SMALL CRAFT OPERATORS. THE
BUILDING SURF AND WAVE ACTION ALONG AREA BEACHES WILL SUPPORT A
HIGH RISK OF RIP CURRENTS ALONG AREA BEACHES THROUGH THURSDAY. ALL
RESIDENT...VISITORS AND MARINERS IN WEST CENTRAL AND SOUTHWEST
FLORIDA SHOULD CONTINUE TO MONITOR THE PROGRESS OF THIS SYSTEM.
FOR ADDITIONAL INFORMATION SEE THE LATEST ADVISORIES BEING ISSUED
BY THE NATIONAL HURRICANE CENTER IN MIAMI.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS SHOULD MONITOR THE WEATHER AND SELF ACTIVATE IF NEEDED.
